As capacitors age, their capacitance can change. If this happens in a circuit, the trimmer capacitor can be adjusted to restore the desired capacitance. When capacitance tolerance is an issue, using a fixed-value capacitor with a tight tolerance will usually equate to a premium price. Using a trimmer capacitor may be more cost effective.
In order to adjust capacitance, a variable capacitor modifies the surface area of its overlapping plates. A variable capacitor, sometimes referred to as a tuning capacitor, is a kind of capacitor in which the capacitance can be mechanically or electrically altered on a regular basis.
Hot melt glue the new capacitor to the top of the board, the jumpers should remain twisted. Tip1: If a capacitor has long enough leads exposed on the front side of the board, you can cut the capacitor off leaving the old leads and solder the new capacitor to the old leads. This method is even faster. See the last picture for an example.
In electronic applications like radios and oscillators, their ability to adjust capacitance by changing surface area, plate spacing, or dielectric material allows for precise control. Anyone interested in electronics must understand these components' operation and maintenance, whether they are electronically or mechanically adjusted.
Tip1: If a capacitor has long enough leads exposed on the front side of the board, you can cut the capacitor off leaving the old leads and solder the new capacitor to the old leads. This method is even faster. See the last picture for an example. Tip 2: You should replace all the electrolytic capacitors, not just the visibly bad ones.
The actual capacitance value can be varied between the minimum and maximum capacitance values for a given trimmer capacitor, but it can never be set to zero. It is worth noting that trimmer capacitors are not polarized. Trimmer capacitors do not boast a good capacitance value tolerance. Sometimes, the tolerances can be as high as -0 to +100%.
